This trick requires 2 controllers. Set the controls to 2 players, single race, no other racers, catch up on, traffic off, and damage on. Have player one drive the Mustang Cobra SVT and player 2 the Corvette Z06. Choose the regular Outback level. When you start, follow the road to the secret with the open ended airplane.
Have player one drive up the secret and slow all the way down when in the airplane. Hit the accelerator slightly, so that half the Mustang is out of it and half of it is still inside. If you fall out, you will need to restart. If done correctly, if you slam the gas, you will not go anywhere. Remain there for about 10 seconds, then have player 2 go through the same secret to the same location that player one is at. You must drive at full speed in the Corvette.
If player 2 hits player one directly in the rear end, the Mustang should fly up in the air and get about 7,200 points.

Go to challenge mode, set the difficulty on advanced, and use only one opponent and give him a M5. Then just choose your car and a short track. Make sure to set it to one lap. By doing this you will
get either $2,100 or $1,500.

Race with a McLaren F1 NFS and get to the point where the wildfires and fire trucks are located. Slide into the side of the 1st fire truck. If you can slide almost parallel to it you can get inside of the truck. This is a good way to get rid of the cops, however you cannot get out again.

If you see a police car ahead, ram it to get him to chase you. Lose the police car and you will get extra points for a hit-and-run. Look for the dirt road shortcuts to lose the police and get ahead of other drivers.

Choose to be the police in Hot Pursuit mode. You will get 25,000 points each time you complete one mini-mission.

Start You're The Cop mode in single player under the beginner difficulty setting. Select either the Crown Victoria or the BMW M5 (the opponents are easier to catch). Now, go to National Forest and catch the fourth and 3rd cars. On the last two, hit the 3rd one to make him lose control, then arrest the 1st place car.
Immediately catch the 2nd player that you forced to lose control to minimize the time to around 138, if done quickly enough. The procedure is quick but easy, giving you over 25,000 points if you throw in a couple of jumps. Now, restart and do it again.

When you are racing and are approaching the finish line, press L2 to do a 360 camera spin. If you manage to get your car on the finish line when you do the 360 camera spin, you can gain 175,000 points, if you include a couple of jumps. *** This only works once, so it must be done accurately.

In a one player race, when your back tires are on the finish line press L2 to do a 360 degree camera spin around the car. If done correctly, your score will now show about 180,000 points. If your back tires are barely on, then you will only receive about 2,000 points. *** This can be performed more than once per race.

This trick is tough to pull off and will require some practice before using it in a race. Get to at least 80 mph. Press the Analog-stick backwards at an angle in the direction that you want to turn, so it is inverting your slide. As soon as you begin to turn, slam and hold the brakes. Force the Analog-stick sequentially around in an extreme circle. Release your brakes when you are about 75% through your turn. Slam your accelerator, and power yourself through the rest of the turn. At the end, it is recommended that you bank the car for a moment, because you do not want the it to fly out of control.

Ok start the game get behind the racer that passes you last of obiously activate your sirens then call in a spike strip since most of them will hit it, it will be sooooo easy to bust them ! please try this!

As you are driving past the gas station, keep going, do NOT take the jump under the semi. then take the next exit, witch goes right. keep going until you see a bundle of bushes on the right. go into the bushes and it will take you to a secret passage in the big dark cave.

First, make sure you stay in first in racing. Now that you are chased by CPU cops. Wait until you have 4 stars and you hear the officer say the word roadblock or spike strip. Okay, here it is. When your appearing a block with spike strip, let your other CPU racers go ahead of you and drive behind them in a distance of 2 seconds 02.00 seconds. They Should go straight to the strip because normally they do not hit the blocking cop cars. If so, you are safe to hit the cop car or the cop cone. If you go ahead of them, that's another story.

Then There's the helicopter part. Let your other opponents go ahead of you and remain in a distance of 1 seconds between you and them. In a distance of 2 seconds between you and the cop helicopter, the copter will throw explosive barrels towards the road, attempting to stop u. Instead, the opponents ahead might hit the barrels and total their cars for a while. There, u're safe to continue your race.
